Tested OS: `Debian sid/experimental loong64` installed with llvm 20.1.3 and 19.1.7
The program runs smoothly in llvm 19.1.7 with the following optimization setting: `-O3 -march=la464 -flto=auto`
In llvm 20.1.3, however I met the runtime error with optimization level `-O1` and above for all test/train/ref sizes. With `-O0` optimization the program can run smoothly.
An example of error message with `-O1` optimization and ref size:
```
445.gobmk: copy 0 non-zero return code (exit code=0, signal=6)
